Where can I safely photograph the Slender Loris at night

The most ethical and reliable place to photograph the Grey Slender Loris is Popham Arboretum in Dambulla. They conduct guided night walks specifically designed to minimize disturbance. They strictly enforce the use of red-light torches, as white light damages the highly sensitive retinas of these nocturnal primates. Bring a fast lens, as flash photography is completely banned.
